Load control operational correction of a blast furnace based on the correlation models

Abstract

The paper uses regression analysis to research the movement dynamics of charge materials along the paths of a blast furnace coneless loader device. The research’s main goal is to consider two main factors when optimizing the loading process of the blast furnace - the opening degree of the charge shutter of the loading device hopper and the inclination angle of the distribution tray. That approach allows the optimization of the loading impact, taking into account the current change in the granulometric parameters of the blast furnace charge. A model for determining the dynamic parameters of the charge flow in the case of its movement along the paths of the blast furnace coneless loading device has been developed.
